    The minimum distance is 4". The maximum distance is the half-spacing for the head, which for standard heads is 7'-6". This distance can be extended to half the distance for extended coverage heads, however these heads must be hydraulically calculated, and in some instances the head will loose it's q-r listing. Small rooms (less than 800 sf) can have heads further off the wall.
